Description: BPSK modulation with BER with and without OFDM
Here are the files for a OFDM modulation. Where in I have used a BPSK modulation and showed the decrease in BER with OFDM. This project was done as a course project under the Guidance of Dr. Dayalan Kasilingam, Umass Dartmouth.

Description: This simulation script set allows for an OFDM transmission to be
simulated. Imagetx.m generates the OFDM signal, saving it as a
windows WAV file. This allows the OFDM signal to be played out a sound
card and recorded back. Imagerx.m decodes the WAV to extract the
data.
settings.m contains all the common settings to specify all the
simulation parameters such as FFT size, number of carriers,
input data source file, input and output WAV files, etc.
